Q

Inferior oblique muscles

A

Innervated by the oculomotor nerve; externally rotates, elevates, and abducts the eye

17
Q

Fibrous Tunic structures

A

Sclera and Cornea

18
Q

Sclera

A

Protective cover for the eye; provides attachment for extrinsic muscles

19
Q

Cornea

A

Admits light into the eye

20
Q

Vascular tunic structures

A

Choroid coat, ciliary body, suspensory ligaments, iris

21
Q

Choroid

A

Provides oxygenation, nourishment, and waste removal services

22
Q

Ciliary body

A

Supports the iris and lens; secretes aqueous humor

23
Q

Iris

A

Controls the diameter of the pupil

24
Q

Suspensory ligaments

A

Suspends the lens behind the pupil

25
Q

Retina

A

Converts light and converts it into electrical signals that the optic nerve sends to the brain

26
Q

Pupil

A

Central opening that lets light into the eyes

27
Q

Anterior chamber

A

Aqueous humor-filled space between the cornea and iris; focus the rays of light that penetrate the eye

28
Q

Posterior chamber

A

Between the iris and lens; production and circulation of aqueous humor

29
Q

Aqueous humor

A

Gives the eye its shape; nourishes the cornea and lens

30
Q

Vitreous humor

A

Protection; maintains eye shape

31
Q

Fovea centralis

A

Responsible for high-acuity vision; densely saturated with cone photoreceptors

32
Q

Macula lutea

A

Responsible for sharp, detailed central vision (visual acuity)

33
Q

Optic disc

A

Where the retina and optic nerve connect; transfers signals from photoreceptors to the optic nerve allowing us to see

34
Q

Optic nerve

A

Transmits electrical impulses from the eye to the brain
